The processing of wood plastic materials

Wood-plastic materials because of the use of living in a lot of places, so many people began to study, then today Xiaobian to tell you about the wood-plastic materials, paint treatment:

After the fluorine-free treatment can be painted: the general plastic in anaerobic conditions, fluoride treatment is to give plastic barrier properties, and in the presence of oxygen fluoride treatment of wood-plastic composite (WPC) surface, often paint and the end Paint Weld WPC is as easy as bonding natural wood. Fluor Seal International, L, USA, USA. P company found that under the conditions of aerobic WPC fluoride treatment also occurs when the oxidation, known as fluorooxidation (fluorooxidation).

According to ASTM's Cross-hatch bonding test, the untreated WPC sheet had a bond strength of 72 g / cm & lt; 2 & gt; while the treated WPC sheet was 182 g / cm & lt; 2 & gt ;. The photo shows that the paint is well bonded to the treated WPC specimen and is poorly bonded to the untreated specimen interface. Fluro-Seal is working with Wisconsin WPC production technology companies to develop off-line fluorooxidation process and HDPE WPC material coating primer technology, and marketing experiments. The reacted fluorine gas was removed by separation of the active aluminum. This technology for the wood-plastic industry is a big breakthrough.
